Teflon elu ọtọ pụrụ iche mkpuchi bụptfedị ka resin isi nke mkpuchi fluorine, aha Bekee maka Teflon, n'ihi ịkpọ okwu, nke a na-akpọkarị Teflon, Teflon, Teflon, Teflon na ihe ndị ọzọ (niile maka nsụgharị nke Teflon).

Teflon na-ekewa n'ime PTFE, FEP, PFA, ETFE ọtụtụ isi ụdị: TEflon PTFE: PTFE (polytetrafluoron) na-abụghị osisi mkpuchi nwere ike nọgidere na-eji na 260 deG C, na a kacha ojiji okpomọkụ nke 290-300 DEG C, dị nnọọ ala esemokwu. ọnụ ọgụgụ, ezigbo eyi nguzogide na nkwụsi ike kemịkalụ mara mma. Teflon FEP: FEP (fluorinated ethylene propylene copolymer) mkpuchi na-abụghị osisi na-agbaze n'oge a na-eme achịcha iji mepụta ihe nkiri na-adịghị mma, na-enwe nkwụsi ike kemịkal dị mma, ihe ndị na-adịghị mma nke ọma, okpomọkụ kachasị elu na-arụ ọrụ bụ 200 ℃. Teflon PFA: PFA (perfluoroalkyl) mkpuchi na-adịghị mma, dị ka FEP, na-agbaze n'oge a na-eme achịcha iji mepụta ihe nkiri porous. Uru nke PFA bụ elu na-aga n'ihu ojiji okpomọkụ nke 260 ℃, ike siri ike, karịsịa adabara maka ojiji nke elu okpomọkụ n'okpuru premise nke mgbochi osisi na kemịkalụ iguzogide na ubi ojiji. Teflon ETFE: ETFE bụ copolymer nke ethylene na tetrafluoroethylene. Resin bụ fluoropolymer kachasị sie ike, na-eme mkpuchi na-adịgide adịgide nke nwere ezigbo nguzogide kemịkalụ na-aga n'ihu na 150 Celsius.

Mgbe ejiri Teflon kpuchie ya, ọ nwere njirimara ndị a:

1, enweghị viscosity: ihe fọrọ nke nta ka ọ bụrụ ihe niile anaghị ejikọta ya na ihe nkiri teflon. Akpụkpọ anụ dị gịrịgịrị na-egosipụtakwa ihe ndị dị mma na-abụghị nke adhesion.

2, okpomọkụ na-eguzogide: Teflon ihe nkiri nwere ezigbo okpomọkụ na-eguzogide na ala okpomọkụ na-eguzogide. Short oge nwere ike idi elu okpomọkụ ka 300 ℃, n'ozuzu n'etiti 240 ℃ ~ 260 ℃ nwere ike ji mee ihe na-aga n'ihu, na doro anya okpomọkụ adịghị aghara, ọ nwere ike na-arụ ọrụ na-na okpomọkụ na-enweghị embrittlement, adịghị agbazekwa na elu okpomọkụ.

3, sliding: Ihe nkiri Teflon nwere obere ọnụọgụ nke esemokwu. Mgbe ibu slide, ọnụọgụ esemokwu na-agbanwe, mana uru dị naanị n'etiti 0.05 na 0.15.

4, mmiri na-eguzogide mmiri: teflon ihe nkiri elu adịghị arapara na mmiri na mmanụ, njikwa mmepụta adịghị mfe ịrapagidesi ike na ngwọta, dị ka obere ihe ruru unyi, dị mfe ihichapụ nwere ike wepụ. Oge nkwụsịtụ dị mkpirikpi, chekwaa oge ma melite arụmọrụ ọrụ.

5, na-eyi nguzogide: n'okpuru ibu dị elu, na-arụ ọrụ nkwụsị nke ọma. N'okpuru ụfọdụ ibu, ọ nwere uru abụọ nke iguzogide iyi na enweghị nrapado.

6. Nguzogide corrosion: Teflon fọrọ nke nta ka ọ bụrụ ihe na-eguzogide ọgwụ corrosion ma nwee ike ichebe akụkụ site n'ụdị ọ bụla nke mmiri ozuzo.
